Acquired Deafblindness

Loop Systems

Most hearing aids and cochlear implants are fitted with a “T” Switch (the “T” means Telecoil). Digital hearing aids and cochlear implants may need to be programmed by an audiologist to activate for use with Telecoil.

When a hearing aid is switched to the “T” position sounds will only be received by the hearing aid or implant via a loop system. Sounds are converted to a magnetic signal via an induction loop or auditory loop. These signals are then picked up by the Telecoil in the hearing device.When no longer using the loop system the “T” switch will need to be changed back to the usual setting. Neck loops, portable loops and fitted room loop systems all work on a similar principle. Check whether your telephone is compatible for use with Telecoil.

Loop systems can improve clarity of sound by reducing echo and background noise for:

  • One-to-one conversations
  • Conversations in meetings/educational settings
  • Television and other audio equipment

With advances in technology FM systems are being used as an alternative to loop systems.

Many public places that
have loop systems installed
will display this symbol.

 

Room Loop Systems

Room loop systems are set up with a loop amplifier connected to cable fitted around the perimeter of the room. Hearing aid users positioned inside the loop receive sounds with reduced background noise. Portable loop systems are another option. A loop works only with hearing aids that are T-switch equipped.
